把地图添加到view即可显示

- (void)viewDidLoad {    [super viewDidLoad];    //配置用户Key    [MAMapServices sharedServices].apiKey = @"76bb9bc3718375ad03acba7c333694c4";    //把地图放在底层    [self.view insertSubview:self.mapView atIndex:0];}//地图懒加载- (MAMapView *)mapView{    if (!_mapView) {        _mapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.bounds), CGRectGetHeight(self.view.bounds))];        _mapView.delegate = self;        _mapView.showsUserLocation = YES;    //YES 为打开定位，NO为关闭定位        [_mapView setUserTrackingMode: MAUserTrackingModeFollow animated:NO]; //地图跟着位置移动        //自定义定位经度圈样式        _mapView.customizeUserLocationAccuracyCircleRepresentation = NO;        //地图跟踪模式        _mapView.userTrackingMode = MAUserTrackingModeFollow;        //后台定位        _mapView.pausesLocationUpdatesAutomatically = NO;        _mapView.allowsBackgroundLocationUpdates = YES;//iOS9以上系统必须配置    }    return _mapView;}

遵守协议 AMapSearchDelegate

高德提供了多种搜索方式，POI搜索（关键字查询、周边搜索、多边形查询），检索现实中真实存在的地物。

提示搜索，就是在还没有输入完全时，根据已有字符进行的搜索

//搜索框激活时，使用提示搜索-(void)updateSearchResultsForSearchController:(UISearchController *)searchController{    //发起输入提示搜索    AMapInputTipsSearchRequest *tipsRequest = [[AMapInputTipsSearchRequest alloc] init];   //关键字    tipsRequest.keywords = _searchController.searchBar.text;   //城市    tipsRequest.city = _currentCity;    //执行搜索    [_search AMapInputTipsSearch: tipsRequest];}//实现输入提示的回调函数-(void)onInputTipsSearchDone:(AMapInputTipsSearchRequest*)request response:(AMapInputTipsSearchResponse *)response{    if(response.tips.count == 0)    {        return;    }    //通过AMapInputTipsSearchResponse对象处理搜索结果    //先清空数组    [self.searchList removeAllObjects];    for (AMapTip *p in response.tips) {            //把搜索结果存在数组        [self.searchList addObject:p];    }    _isSelected = NO;    //刷新表视图    [self.tableView reloadData];}

点击进行poi搜索

//周边搜索- (IBAction)searchAction:(id)sender {    //初始化检索对象    _search = [[AMapSearchAPI alloc] init];    _search.delegate = self;    //构造AMapPOIAroundSearchRequest对象，设置周边请求参数    AMapPOIAroundSearchRequest *request = [[AMapPOIAroundSearchRequest alloc] init];    //当前位置    request.location = [AMapGeoPoint locationWithLatitude:_currentLocation.coordinate.latitude longitude:_currentLocation.coordinate.longitude];    //关键字    request.keywords = _searchController.searchBar.text;    NSLog(@"%@",_searchController.searchBar.text);    // types属性表示限定搜索POI的类别，默认为：餐饮服务|商务住宅|生活服务    // POI的类型共分为20种大类别，分别为：    // 汽车服务|汽车销售|汽车维修|摩托车服务|餐饮服务|购物服务|生活服务|体育休闲服务|    // 医疗保健服务|住宿服务|风景名胜|商务住宅|政府机构及社会团体|科教文化服务|    // 交通设施服务|金融保险服务|公司企业|道路附属设施|地名地址信息|公共设施    //    request.types = @"餐饮服务|生活服务";    request.radius =  5000;//<! 查询半径，范围：0-50000，单位：米 [default = 3000]    request.sortrule = 0;    request.requireExtension = YES;    //发起周边搜索    [_search AMapPOIAroundSearch:request];}//实现POI搜索对应的回调函数- (void)onPOISearchDone:(AMapPOISearchBaseRequest *)request response:(AMapPOISearchResponse *)response{    if(response.pois.count == 0)    {        return;    }    //通过 AMapPOISearchResponse 对象处理搜索结果    [self.dataList removeAllObjects];    for (AMapPOI *p in response.pois) {        NSLog(@"%@",[NSString stringWithFormat:@"%@\nPOI: %@,%@", p.description,p.name,p.address]);        //搜索结果存在数组        [self.dataList addObject:p];    }    _isSelected = YES;    [self.tableView reloadData];}

规划路径查询（驾车路线搜索、公交换成方案查询、步行路径检索），提前知道出行路线

//规划线路查询- (IBAction)findWayAction:(id)sender {    //构造AMapDrivingRouteSearchRequest对象，设置驾车路径规划请求参数    AMapWalkingRouteSearchRequest *request = [[AMapWalkingRouteSearchRequest alloc] init];    //设置起点，我选择了当前位置，mapView有这个属性    request.origin = [AMapGeoPoint locationWithLatitude:_currentLocation.coordinate.latitude longitude:_currentLocation.coordinate.longitude];    //设置终点，可以选择手点    request.destination = [AMapGeoPoint locationWithLatitude:_destinationPoint.coordinate.latitude longitude:_destinationPoint.coordinate.longitude];//    request.strategy = 2;//距离优先//    request.requireExtension = YES;    //发起路径搜索，发起后会执行代理方法    //这里使用的是步行路径    [_search AMapWalkingRouteSearch: request]; }//长按手势响应方法，选择路径规划的终点，手势自己加- (void)handleLongPress:(UILongPressGestureRecognizer *)gesture{    if (gesture.state == UIGestureRecognizerStateBegan)    {       //在地图上长按的位置        CGPoint p = [gesture locationInView:_mapView];        NSLog(@"press on (%f, %f)", p.x, p.y);    }     //转换成经纬度    CLLocationCoordinate2D coordinate = [_mapView convertPoint:[gesture locationInView:_mapView] toCoordinateFromView:_mapView];   //赋值给目标点    _destinationPoint = [[MAPointAnnotation alloc] init];    _destinationPoint.coordinate = coordinate;}

执行路径搜索后会执行代理方法

//实现路径搜索的回调函数- (void)onRouteSearchDone:(AMapRouteSearchBaseRequest *)request response:(AMapRouteSearchResponse *)response{    if(response.route == nil)    {        return;    }    //通过AMapNavigationSearchResponse对象处理搜索结果    NSString *route = [NSString stringWithFormat:@"Navi: %@", response.route];    AMapPath *path = response.route.paths[0]; //选择一条路径    AMapStep *step = path.steps[0]; //这个路径上的导航路段数组    NSLog(@"%@",step.polyline);   //此路段坐标点字符串    if (response.count > 0)    {        //移除地图原本的遮盖        [_mapView removeOverlays:_pathPolylines];        _pathPolylines = nil;        // 只显⽰示第⼀条 规划的路径        _pathPolylines = [self polylinesForPath:response.route.paths[0]];        NSLog(@"%@",response.route.paths[0]);        //添加新的遮盖，然后会触发代理方法进行绘制        [_mapView addOverlays:_pathPolylines];    }}

每次添加路线，区域，或者大头针等都会触发下面的代理方法

//绘制遮盖时执行的代理方法- (MAOverlayRenderer *)mapView:(MAMapView *)mapView rendererForOverlay:(id <MAOverlay>)overlay{    /* 自定义定位精度对应的MACircleView. */    //画路线    if ([overlay isKindOfClass:[MAPolyline class]])    {       //初始化一个路线类型的view        MAPolylineRenderer *polygonView = [[MAPolylineRenderer alloc] initWithPolyline:overlay];        //设置线宽颜色等        polygonView.lineWidth = 8.f;        polygonView.strokeColor = [UIColor colorWithRed:0.015 green:0.658 blue:0.986 alpha:1.000];        polygonView.fillColor = [UIColor colorWithRed:0.940 green:0.771 blue:0.143 alpha:0.800];        polygonView.lineJoinType = kMALineJoinRound;//连接类型        //返回view，就进行了添加        return polygonView;    }    return nil;}
